I heard the Makaya McCraven album. It was OK, but not something I find myself wanting to return to. I've used this phrase before but I'll used it again, it didn't really scratch my itch for jazz. Whatever sort of music it is, and it's kind of groove heavy ambient music, it doesn't give me the same kicks I'm looking for in a jazz record, and I'm not that enamored of groove heavy ambient music. It funny, having grown up in the world of groove music -- JB and Sly and PFunk, et al (and spend a lot of time with PFunk's music and with the band members and delving into the group's history as one point), I've kind of drifted away from groove music in my later years (notwithstanding my period listening to a lot of Franco and other Congolese rumba a few months back). I haven't heard the Iyer.
